"When my husband and I had the good fortune of meeting Martha Knapp, our dream of owning a home on Cape Cod was still years away. She patiently and methodically developed a relationship with us, showing us many properties over months and months. She knows the area so well as a Realtor, but also as a parent and active community member that she is the perfect person to educate and inspire a move to Cape Cod. When we fell in love with a unique home, Martha worked so skillfully with us and the other Realtor, lawyers and our lender to take what seemed impossible and make it into a reality. She walked us literally through every step following up on all the details, she was methodical and organized with the entire process from beginning to end. As a former military couple, we have moved many times over our 25-year marriage and have worked with many Realtors, and were perhaps a bit jaded to the profession in general. Working with Martha and Kinlin Grover has really changed our impression. She took a genuine interest in us as people, not as potential income. She has a passion for what she does that is refreshing and we now feel blessed to have her as a neighbor and friend in the community. We can't recommend her more highly to anyone thinking of buying or selling a home in this area... we love you, Martha!" - Maura & Marty

"I want to thank you for all your support, kindness, advocacy and real estate expertise with the listing, marketing, and sale of my Cape Cod home. I was so excited to be moving to Santa Fe, NM, after so many years on the Cape. The process of listing and selling brought up feelings of vulnerability, trust, and honesty. All along the way you projected an honest, truthful and supportive approach. I feel as women, we empowered each other to create the sale and work together in harmony to achieve a goal. And I might add in a very short period of time! I am very grateful for your presence in my life, your future clients are very fortunate to have you as their guide on the real estate journey." - Caroline

"We recently purchased a home on the Cape with the outstanding help and professionalism from Martha Knapp. From the beginning, she listened to what we were looking for in a home and made the process so easy and enjoyable. Her amazing attention to detail and professional judgment with all that went into this purchase was so appreciated. She went to great lengths to show us the surrounding area, including medical facilities, stores, restaurants and even shortcuts when the summer traffic returns. My husband and I can't say enough about the positive experience we recently had with Martha. You will be a very lucky to connect with Martha Knapp!" - Gail & Steve

"My husband and I were extremely pleased with our experience with Martha Knapp. She was friendly and professional, honest and informative, and ready to help us throughout our process. We felt that she worked for us, gathering information between meetings and really listening to our feedback when we were together. Once we found the right property, she was responsive and supportive throughout the negotiation process. Between the signing of the P&S and the closing, Martha continued to remain in contact, giving us information about everything from inspectors to local area points of interest that would appeal to all members of our family. She was attentive right through the closing and remained in touch afterward to ensure that we were satisfied with the process. We are thrilled with our purchase and have already recommended Martha to friends. She was wonderful to work with, and a true expert in the world of Harwich real estate." - Rebecca & Matt

"Martha is an amazing Real Estate Agent! She handled every curve ball we were thrown quickly and professionally, she does a lot of behind the scenes work to get the job done i.e. speaking to the mortgage lender, my attorney, and the other agent. Martha kept me informed of what was going on but she was able to handle most of the problems without involving me. She always works in the best interest of her client. I trusted Martha and her judgment immediately - she has great instincts; she's friendly, warm and funny! I was so happy that I not only got THE BEST agent on the Cape but I also met a new friend. I can't say enough nice and true things about Martha. Every time after I spoke or met Martha in person, the first words out of my mouth were "I just love that Martha!". Martha is truly amazing!!" - Caroline

About Martha
Cape Cod has always been a part of my life. Growing up in a suburb of Boston, I often traveled to the Cape as a young child to visit relatives and enjoyed camping each summer with my family in various areas across Cape Cod. Our days were spent either exploring or at the beach, and nights were filled with campfires and stories. We would collect sharks' teeth at the Head of the Meadow Beach in Truro, climb the dunes, buy great fudge in P-Town, and visit all the quaint artisan shops along Route 6A.

In 1986 I was fortunate to move to the Cape and enjoyed the beauty of the area year-round when I opened a business in West Dennis. In 1994 my husband and I moved to Harwich with our two children and we have called it home ever since.

Although I love all the seasons on Cape Cod, my favorite is Fall. The traffic has thinned, the air is crisp, and the ocean is beautiful. The bright red of a cranberry harvest, against a beautiful blue sky with billowy white clouds is picture-perfect. 

I build relationships with my clients and everyone involved in a transaction. This helps assure a smooth transaction that can ease the stress when unexpected things arise. Doing a job well done and taking care of my client is important to me and it shows. If you are selling your home I understand the often conflicting emotions and can help manage them.

I believe the Cape offers more than a location - it's a way of life. Each of the many villages offers a unique character all its own. Whether you're looking to relocate your primary residence or purchase a second home, the house you choose should reflect your personality and lifestyle. When the beauty of the area touches your soul, you know you have found your home. I would love to help you find your own Cape Cod.
